Flow-induced Nonequilibrium Self-assembly in Suspensions of Stiff, Apolar, Active Filaments

Active bodies in viscous fluids interact hydrodynamically through self-generated flows. Here we study spontaneous aggregation induced by hydrodynamic flow in a suspension of stiff, apolar, active filaments. Lateral hydrodynamic attractions in extensile filaments lead, independent of volume fraction, to anisotropic aggregates which translate and rotate ballistically. Lateral hydrodynamic repulsion in contractile filaments lead, with increasing volume fractions, to microstructured states of asters, clusters, and incipient gels where, in each case, filament motion is diffusive. Our results demonstrate that the interplay of active hydrodynamic flows and anisotropic excluded volume interactions provides a generic nonequilibrium mechanism for hierarchical self-assembly of active soft matter.

Probing the free-streaming of dark matter with the Lyman-alpha forest

The Lyman-alpha forest in QSO absorption spectra is a sensitive probe of the matter distribution as well as the physical state of the Intergalactic Medium. I will present constraints on the free-streaming of dark matter particles and the thermal and ionization history of the Intergalactic Medium.

What are the implications of a dynamic spiral-armed particle propagation model on various aspects of Galactic Cosmic Rays?

Over the years, significant effort has been devoted to understanding cosmic ray propagation in the galaxy, based on the energy dependence of the secondary to primary ratios in galactic cosmic rays. We develop a fully three dimensional numerical code describing the diffusion of cosmic rays in the Milky Way. This code enables us to explore a model in which a large fraction of the cosmic ray acceleration takes place in the vicinity of galactic spiral arms, with these spiral arms being dynamic: particle density distributions become dependent on the energy, with spectral indices of CRs becoming ``harder" in the spiral arms than outside the arms. Secondary to primary particle ratios and the effect on the K-capture isotopes are reported.

Pattern Formation and Collective Phenomena in Biological Systems

Reaction-diffusion dynamics endows cells with the capacity for accurate positioning, control of length, and timing of processes. Protein systems in cells employ different types of spatio-temporal patterns to ensure precise cell division and guide intracellular processes. The length of biopolymers is regulated by the interplay between polymerization kinetics and patterns of molecular motors. Under which conditions protein patterns emerge, and how these patterns are regulated by biochemical and geometrical factors are major aspects of current research. We will discuss general design principles of such biological pattern forming systems.

Klosk Lecture Series:
Frontiers of Fundamental Physics

At the frontiers of physics we search for the principles that might unify all the forces of nature and we strive to understand the origin and history of the universe. In this lecture I shall describe some of the the questions that we ask and some of the proposed answers. I shall also discuss what it might mean to have a final theory of fundamental physics and whether we are capable of discovering it.

Complex Fluid Interfaces in Electric Fields: Belted Drops, Patchy Membranes, and Vesicle Drums

I will present some of our recent experimental observations on ``complex’’ fluid-fluid interfaces - surfactant-laden and particle-covered drops, and vesicles (drops encapsulated with lipid bilayer membranes)- in uniform DC and AC electric fields. The coupling of the electric field induced flow and complex mechanics of the interface drives peculiar (and still to be explained) behaviors: drum-like or asymmetric dumbbell shapes of a vesicle; domain nucleation and dissolution in multicomponent membranes; particle assembly in dynamic vortices; drop wobbling. Implications to the design of patchy particles and electrorheology of emulsions will be discussed.

Studying the Expansion of the Universe with BOSS quasars

After five years of observations, the Baryon Oscillation Spectroscopic Survey (BOSS) was finished in July. During these years, it has used the SDSS telescope to obtain spectra of 1.5 million galaxies to get very accurate measurements of the Baryon Acoustic Oscillations (BAO) scale at redshift z ~0.5. Roughly 20% of the fibers of the spectrograph, however, are pointing to high redshift quasars with the goal of detecting the BAO feature in the clustering of the intergalactic medium, using a technique known as the Lyman alpha forest. In this talk I will overview several recent results from the Lyman alpha forest working group in BOSS, including the measurement of BAO at z=2.4 both from the auto-correlation of the Lyman alpha absorption, and from its cross-correlation from quasars. I will also present preliminary results on the cosmological parameters constrains obtained when combining all BOSS BAO analyses with Cosmic Microwave Background and supernovae probes, including the most precise measurement of the current expansion of the Universe.

Constraining Galaxy Feeding and Feedback with MaNGA

A central issue in galaxy evolution is understanding the "baryon cycle," namely how gas is accreted onto galaxies and expelled in galactic winds. Gas flows are difficult to measure directly, but disk galaxy nebular oxygen abundance measurements can provide powerful indirect constraints. I will present some early work form the SDSS-IV MaNGA survey which will obtain spatially resolved oxygen abundance measurements of around 5,000 disk galaxies.
